Abstract:
Vitiligo is a common acquired Thypornelanotic disease but the pathogenesis is still unknown and also the traatment is still unsatisfactory. The introduction in 1947 of psoralen therapy in vitiligo by El Mofty announced a new era in the treatment of this cosmetically disfiguring disease. Many investigators have developed therapeutic regimens for both topical and systemic poralen using various ligbt sources. The erythema action spectrum in UVA range of psoralen were defined, which consequently enabled the development of a more accurate regimen, namely psoralen and UVA(FUVA, exposure. The present study was undertaken to evaluate the efficacy of topical PUVA therapy in patients with vitiligo and to compare the result of PUVA therapy according to the age, sex, type of disease, total exposure dose, duration of disease nd involved site. Twenty one patients selected in the Department of Dermatology of Kyung hee University Hospital with various clinical types of vitiligo were treated with 03% 8-MOP ointment followed by exposure to longwave ultraviolet energy. Clinical response was graded as follows: Grade 0: No repigmentation Grade 1; Up to 25% repigmentaton Grade 2; 25% to 50% repigmentation Grade 3; 50% to 90% repigmentation Grade 4; Greater than 90% repigmentation A responsive case wss defined as a case with greater than 25% repigmentation. A effective case was defined as a case with greater than 50;o repigmentation.
